Could Hunt-class escort destroyers technically be regarded as sloops?
Short answerThey share a sloop design ancestry, but their increased machinery power and speed make them a different kind of escort.
NotesThe Hunt is treated as a sloop-derived hull whose machinery and speed change its classification. The discussion recalls an early single-boiler proposal followed by a two-boiler arrangement producing roughly 27.5 knots. That speed is given as the reason for the escort-destroyer designation. Some sloop designs are also described as leaving machinery space and connections for an additional boiler. The argument concerns the difference between the ship as designed for treaty purposes and the power that could later be installed.
